Why Light Distribution Matters in Greenhouses
In a commercial greenhouse, the light available to a crop depends not only on how much light enters the structure, but also on where that light reaches the canopy. On clear days, sunlight enters mainly from one direction. In tall or dense crops, upper leaves may receive strong light while leaves in the middle and lower canopy remain shaded.

This issue is especially relevant in tall fruiting crops such as tomatoes, cucumbers, and peppers. It can also matter in flower and nursery production, where differences in canopy exposure need to be managed carefully.
Light-diffusing materials scatter incoming sunlight across a wider range of angles. This can reduce strong contrasts between bright and shaded areas and help light reach more parts of the canopy. For a detailed explanation, see Diffuse Light vs. Direct Light in Greenhouses.
INSONSHADE Climate Screens for Light Management
INSONSHADE Diffusa screens are one option for managing light distribution in commercial greenhouses. For a canopy-focused discussion, see How to Improve Light Distribution in a Greenhouse Tomato Canopy.
For projects that require closer control of light distribution, Diffusa can be considered alongside diffuse glass, reflective ground covers, and other light-management measures. Screen selection and operation should also be coordinated with shading and ventilation strategies. Together, these measures can reduce the contrast between bright and shaded areas and improve how light reaches different parts of the canopy.

Diffusa climate screens use white light-diffusing strips in a textile structure to scatter incoming sunlight. This helps reduce strong direct sunlight and creates a more even light environment inside the greenhouse.
Different specifications are available for shading rate, light transmission, and energy-saving performance. This allows greenhouse operators and project buyers to select a screen based on the crop, greenhouse structure, local climate, and seasonal light conditions.
Custom Options for Commercial Greenhouse Projects
Light-management requirements vary from one greenhouse project to another. For example, a tomato greenhouse in a high-radiation region may need a stronger combination of shading and diffusion. A nursery or flower greenhouse may need softer light while maintaining higher light transmission. A high-tech glass greenhouse may require a screen that is compatible with an automated curtain system.
INSONSHADE supports project-based customization for climate screens, including:
- 1. Shading rate
- 2. Light transmission
- 3. Energy-saving level
- 4. Screen width
- 5. Internal curtain system compatibility
- 6. OEM and ODM requirements
